one piece tcg big mom deck list OP11 Blue/Purple Monkey.D.Luffy Decklist and Smoothie ST07 Big Mom Pirates Deck

While there are other worthy contenders such as Blue Elemental Blast and even the recent Mystical Dispute that costs only 1 Blue Mana , Counterspell offers blanket protection for 2 Blue Mana

1 Necrogen Communion

It also serves as a finisher of sorts

Steelswarm Operator Steelswarm Operator isnt the first 2-cost mana dork for artifacts (Oaken Siren, Guidelight Optimizer), but its the first that produces additional mana to pay for abilities from artifacts

Ive run variations of this list that are more control heavy or more combo heavy, leaning in on sacrificing creatures with +1/+1s on them to a [Card]Cartel Aristocrat[/Card] when a [Card]Doubling Season[/Card] effect is in play for a protection from all colours but the current list is go wide and tall, with the recursion suite supporting against standard removal and consistent wraths
